I'm going to move this to "Psychology" and out of trading since it's non-specific.
However, I'd like to comment that I also have a tendency to trade against the trend - especially when it's an extremely strong trend. If you think logically about this, it should be obvious that it's a bad idea. Now that I've developed a bit more, I find that I'm able to catch myself as I look at a trend and call it "irrational" merely because it's rocketing towards never seen before heights or trying to bottom pick just because something is at a significant low.
The programmed nature to "be right" seems to be more important than actually trading right. When you think about it, it's better to be right for the wrong reason. Follow the flow - don't try swimming against the current, even if you know you're right. Right, wrong - neither matter when you don't have the power to influence. You are not a voice in the crowd, shouting for logic. You're just a voice in the crowd. Shout what they shout.
